The Rangers went hitless in six at-bats with runners in scoring position and grounded into two double plays during a loss to the Los Angeles Dodgers at Glendale, Ariz.

The Dodgers scored their runs on Hanley Ramirez' first-inning homer against LHP Martin Perez, who again had problems throwing the fastball for strikes.

"That's what spring training is for,'' Perez said. "I have to attack more with my fastball. My (other pitches) are good. The only think I need to work on is my fastball.''

The Rangers are 1-6-1 in the last eight games.

The Arms: Perez attributed his command problems to falling off to the left side in his delivery rather than driving toward the plate. He gave up three walks in three innings and has allowed five walks in five innings overall. … LHP Michael Kirkman had three scoreless innings, giving him five scoreless innings for the spring. He had a 2.45 ERA in 11 innings last spring but struggled in the regular season. …

The Bats: The Rangers scored the run once in two chances with a runner at third and fewer than two outs. In the first, 1B Mitch Moreland failed by hitting a grounder to the left side of a drawn-in infield. In the seventh, DH Jurickson Porfar put a grounder in the right spot on the right side to score the run. .. CF Leonys Martin reached in the third on a walk but was thrown out trying to steal second. Martin has been thrown out in both steal attempts this spring. He had 36 steals in 45 tries last season.

The Gloves: In the first, Martin raced forward to make a diving catch on a sinking liner to shallow center by Juan Uribe. … In the second, Perez broke off the mound well to cut off a bunt by speedy Dee Gordon and get the out at first. … In the fifth, Gordon read Kirkman's move to the plate and easily stole second.

On deck: RHP Tanner Scheppers, still under consideration for a rotation spot, will start on Saturday against the Los Angeles Dodgers at Surprise, Ariz. (KESN-FM, 103.3.) LHP Robbie Ross, in the same situation as Scheppers, is also scheduled to appear.

INTERNATIONAL FOCUS: Teen-aged OF Nomar Mazara, one of the Rangers' pricey acquisitions on the Dominican Republic free-agent market, had a busy day that included three good plate appearances against major-league pitchers.

In the morning "B'' game against Kansas City, Mazara pulled a liner to right-center for a double against RHP P.J. Walters, who has made 40 major-league appearances. Mazara, 18, also worked RHP Greg Holland, an All-Star selection last season, for a walk. Holland allowed only 18 walks in 67 innings last season.

In the afternoon game, Mazara worked a walk against Brandon League, an All-Star closer with Seattle in 2011. Mazara ended his day by grounding into a force out against minor-league LHP Tom Windle.

The Rangers list Mazara at 6 feet 4 and 200 pounds. He likely will open the season at high Class A Myrtle Beach of the Carolina League. Mazara hit .236 with 13 homers, 62 RBIs and a .692 OPS in his first full professional season last year with low Class A Hickory of the South Atlantic League.
